Bayer’s Vitrakvi (larotrectinib) has been granted traditional approval by the US Food and Drug Administration (FDA) to treat neurotrophic receptor tyrosine kinase (NTRK) gene fusion-positive solid tumours. The TRK inhibitor is now fully authorised for use in adult and paediatric patients with solid tumours that do not have a known acquired resistance mutation, are metastatic or where surgical resection is likely to result in severe morbidity, and have no satisfactory alternative treatments or have progressed following treatment. The FDA first approved Vitrakvi in 2018 under its accelerated approval pathway, under which the US regulator may approve therapies for serious diseases like cancer earlier, on the condition that companies conduct studies to confirm the anticipated clinical benefit. Tumours with NTRK gene fusion produce an altered TRK protein, which causes the uncontrolled growth of cancer cells. Vitrakvi is designed to block the action of this protein to prevent the excessive growth of cancer cells and slow the worsening of the disease. TRK fusion cancer can occur in any part of the body, including the lungs, thyroid, colon, pancreas and salivary glands. Commenting on the authorisation, Andrea Ferris, president and chief executive officer of the non-profit lung cancer foundation LUNGevity, said: “The full approval of Vitrakvi by the FDA is a welcome step forward, solidifying its place as a treatment option for patients with NTRK gene fusion-positive cancers. “This milestone not only benefits patients today but also paves the way for further advancements in NTRK gene therapies in the future.” The FDA’s latest decision on Vitrakvi was supported by positive data from three open-label trials, which included adult and paediatric patients with unresectable or metastatic solid tumours with an NTRK gene fusion. Pooled efficacy results demonstrated an overall response rate of 60%, a complete response rate of 24% and a partial response rate of 36% for Vitrakvi-treated patients, as well as median duration of response of 43.3 months. Chandra Goda, executive director, US Vitrakvi brand lead, said: “This first full approval of an NTRK inhibitor by the FDA represents the culmination of research and dedication by the Bayer team.”

As biomarker testing and the demand for tumor-agnostic therapies rise, ROZLYTREK can potentially target a specialized yet valuable market segment. While competition from other TRK inhibitors, such as larotrectinib (VITRAKVI), may influence growth, its ability to penetrate the CNS provides a distinct advantage. LAS VEGAS, March 12, 2025 /PRNewswire/ -- DelveInsight's " ROZLYTREK Market Size, Forecast, and Market Insight Report" highlights the details around ROZLYTREK, an inhibitor of the tropomyosin receptor tyrosine kinases (TRK) TRKA, TRKB, and TRKC (encoded by the neurotrophic tyrosine receptor kinase [NTRK] genes NTRK1, NTRK2, and NTRK3, respectively), proto-oncogene tyrosine-protein kinase ROS1, and ALK with IC50 values of 0.1 to 2 nM. The report provides product descriptions, patent details, and competitor products (marketed and emerging therapies) of ROZLYTREK. The report also highlights the historical and forecasted sales from 2020 to 2034 segmented into 7MM [the United States, the EU4 (Germany, France, Italy, and Spain), the United Kingdom, and Japan]. Roche's ROZLYTREK (entrectinib) Overview ROZLYTREK is a tumor-agnostic therapy that introduces a novel approach to cancer treatment. Its active ingredient, entrectinib, inhibits tropomyosin receptor tyrosine kinases (TRKA, TRKB, and TRKC), which are encoded by the NTRK1, NTRK2, and NTRK3 genes. It also targets ROS1 and ALK, with IC50 values ranging from 0.1 to 2 nM, while showing weaker inhibition of JAK2 and TNK2 (IC50 > 5 nM). The primary active metabolite, M5, exhibits similar inhibitory activity against TRK, ROS1, and ALK. Fusion proteins involving TRK, ROS1, or ALK kinase domains can promote tumor growth by excessively activating downstream signaling pathways, leading to uncontrolled cell proliferation. Entrectinib has demonstrated both in vitro and in vivo efficacy in inhibiting cancer cell lines across multiple tumor types carrying NTRK, ROS1, or ALK fusions. Additionally, it achieves steady-state brain-to-plasma concentration ratios between 0.4 and 2.2 in animal studies (mice, rats, and dogs) and has shown anti-tumor effects in mice with intracranial tumors driven by TRKA and ALK. ROZLYTREK is an orally administered, once-daily treatment approved for NTRK fusion-positive solid tumors and ROS1-positive NSCLC in several countries, including Australia, Canada, the EU, Israel, Japan, New Zealand, South Korea, Taiwan, and the US, with additional regulatory reviews ongoing worldwide. The recommended ROZLYTREK dosage for ROS1-positive NSCLC is 600 mg once daily, with or without food, until disease progression or unacceptable toxicity. For NTRK fusion-positive solid tumors, the ROZLYTREK dosage guidelines are as follows: Adults and pediatric patients with a body surface area (BSA) of ≥1.51 m²: 600 mg once daily Pediatric patients older than 6 months: 300 mg/m² to a maximum of 600 mg Pediatric patients between 1 month and 6 months: 250 mg/m² once daily Learn more about ROZLYTREK projected market size for ROS1 NSCLC @ ROZLYTREK Market Potential Receptor Tyrosine Kinase (ROS1) is an essential transmembrane receptor protein that regulates key cellular functions such as apoptosis, survival, differentiation, proliferation, migration, and transformation. It plays a pivotal role in various cancers, including glioblastoma, colorectal cancer, gastric adenocarcinoma, inflammatory myofibroblastic tumor, ovarian cancer, angiosarcoma, and NSCLC. A ROS1 inhibitor is a drug designed to block the activity of abnormal ROS1 fusion proteins present in certain cancer cells. By inhibiting this protein, these inhibitors help restrict cancer cell growth and metastasis. As a type of targeted therapy, ROS1 inhibitors also act on multiple kinases, including Anaplastic Lymphoma Kinase (ALK) and Mesenchymal Epithelial Transition (MET), alongside ROS1. These inhibitors specifically target the kinase domain of ROS1, with conventional kinases classified into DFG-in (active, type I) and DFG-out (inactive, type II) based on their domain structure. For patients with stage IV ROS1-positive NSCLC, treatment with a ROS1 tyrosine kinase inhibitor (TKI) is recommended. ROS1 inhibitors have demonstrated remarkable efficacy in treating NSCLC, encompassing both approved therapies and emerging treatments under development. They have significantly advanced NSCLC management, establishing themselves as a crucial therapeutic approach. The current market for ROS1-positive NSCLC is largely dominated by TKIs such as XALKORI. According to DelveInsight's analysis, the market size for ROS1 inhibitors in NSCLC across the 7MM was valued at approximately USD 290 million in 2023, with the United States contributing the largest share. The market for ROS1 inhibitors is projected to experience substantial growth in the coming years. This expansion is driven by rising biomarker testing rates, a growing number of cancer diagnoses, increased awareness of ROS1 mutations, and the introduction of next-generation ROS1 TKIs. These advanced therapies offer improved CNS penetration and a broader range of coverage against ROS1 resistance mutations compared to first-generation TKIs.

Several months into a multiyear quest to “rigorously prioritize” its pipeline, Takeda is cutting a handful of programs. The company revealed the changes on Thursday in its third-quarter earnings report , in which CEO Christophe Weber announced plans to retire in June 2026. Weber last year laid out the road map for a broad restructuring aimed at simplifying the company’s structure, removing layers and broadening roles. Takeda has also made several pipeline cuts over the last year, and it’s now ending work on a Phase 3 program for soticlestat in a form of epilepsy. In 2024, soticlestat failed separate Phase 3 trials in Dravet syndrome and Lennox-Gastaut syndrome, and Takeda had already discontinued development in the latter condition. After meeting with the FDA about an indication for Dravet syndrome, a genetic form of epilepsy, regulators said current data “would not be capable of demonstrating substantial evidence of effectiveness,” Takeda said. The company added that soticlestat’s financial impact on full-year results is “expected to be immaterial.” Another Phase 3 program is also getting the boot. Takeda said it’s stopping work on the Exelixis-partnered drug Cabometyx in combination with Roche’s Tecentriq in metastatic castration-resistant prostate cancer. Cabometyx was originally developed by Exelixis, and then Takeda inked a deal for commercial and development rights in Japan in 2017. The drug is currently approved in the US for thyroid cancer, hepatocellular carcinoma and renal cell carcinoma. Takeda said the decision to pull the Cabometyx-Tecentriq combo in metastatic castration-resistant prostate cancer was “based on the trial results and assessment of Takeda’s development strategy.” A Phase 1 trial for TAK-500 in solid tumors was also closed “due to dose-limiting toxicities.” For the second consecutive quarter, Takeda raised its full-year revenue guidance. The company said in October that it expects full-year revenue to come in flat or slightly increase. It now expects an increase in revenue by a low single-digit percentage. The company also touted three Phase 3 readouts coming in 2025, including oveporexton in narcolepsy type 1, zasocitinib in psoriasis, and rusfertide for a rare blood disorder called polycythemia vera. “We are focused on advancing our promising late-stage pipeline and preparing for future launches. I couldn’t be more excited about what lies ahead for Takeda,” Weber said during an analyst call.
